General Safety

TIRES

HANDLING TIRES
If tires are not used under the specified conditions, they may overheat and burst or be cut and burst by sharp
stones on rough road surfaces. This may lead to serious injury or damage.
To maintain safety, always keep to the following conditions:
• Inflate the tires to the specified pressure. Abnormal heat is generated particularly when the inflation pressure is
too low.
• Use the specified tires.
The values given in this manual for the tire inflation pressure and permissible speed are general values. The actual
values may differ depending on the type of tire and the condition under which they are used. For details, please
contact your Komatsu distributor or tire maker.
If the tires become hot, a flammable gas is produced, and this may ignite. It is particularly
dangerous if the tires become overheated when the tires are under pressure. If the gas
generated inside the tire ignites, the internal pressure will suddenly rise, and the tire will
explode, and this may lead to serious personal injury. Explosions differ from punctures or
tire bursts, because the destructive force is extremely large. Therefore, the following oper-
ations are strictly prohibited when the tire is under high internal pressure:
• Welding the rim
• Building fires or carrying out welding near the wheel or tire.
If you do not understand the proper procedure for carrying out maintenance or replacement of the wheel or tire,
and you use the wrong method, the wheel or tire may burst and cause serious injury or damage. When carrying out
such maintenance, please consult your Komatsu distributor or tire maker.
STORING TIRES AFTER REMOVAL
• As a basic rule, store the tires in a warehouse which unauthorized persons cannot enter. If the tires are stored
outside, always erect a fence around the tires and put up "No Entry" and other warning signs that even young
children can understand.
• Stand the tire on level ground, and block it securely so that it cannot roll or fall over.
• If the tire should fall over, get out of the way quickly. The tires for construction equipment are extremely heavy,
so trying to hold the tire may lead to serious injury.
